9x^4−64y^2

Please hurry! 25 points for the right answer.

(3 x + 8 y) (3 x − 8 y)

Step-by-step explanation:

Rewrite 9 x 2 as (3 x) 2.

(3 x) 2 − 64 y 2 Rewrite 64 y 2 as (8 y) 2.

(3 x) 2 − (8 y) 2 Since both terms are perfect squares, factor using the difference of squares formula, a 2 − b 2 = (a + b) (a − b) where a = 3 x and b = 8 y.

(3 x + 8 y) (3 x − (8 y)) Multiply 8 by − 1.

(3 x + 8 y) (3 x − 8 y).

Hope this helps, have a nice day! :D
